[0033] The working principle of this utility model is as follows: During subway construction, it is necessary to protect some foundation pits and dangerous areas to prevent unauthorized personnel from entering and getting injured. This also protects the site and prevents disruption to normal construction. When using the safety protection device for subway construction, the lower convex plate support base 12 and the upper convex plate support base 22 at the bottom of the first support component 1 and the second support component 2 need to be positioned as required. Then, the lower convex plate support base 12 and the upper convex plate support base 22 are fixed to the ground using fastening screws. Then, the adjacent first support component 1 and second support component 2 are... To connect, first, fit and snap one end of the lower convex plate support base 12 with one end of the upper convex plate support base 22. Then, use fastening screws to secure the lower convex plate support base 12 and the upper convex plate support base 22 together, thus securing adjacent safety protection devices. Continue connecting the safety protection devices sequentially until the area requiring enclosure is isolated. If it is necessary to unfold the safety protection device during installation, simply rotate the two sets of threaded rods 31 to separate them from the threaded holes 11 on the outer surfaces of the lower convex plate support base 12 and the upper convex plate support base 22. Then, the lower convex plate... The support base 12 is positioned on the ground. Then, the second vertical support frame 23 is pulled to move the first connecting component 3 and the second connecting component 4 laterally. At the same time, the first connecting component 3 and the second connecting component 4 will cause the second connecting column 34 to slide inside the first insertion hole 15 and the second insertion hole 33. Moreover, the second vertical support frame 23 will cause the first connecting column 25 to slide inside the second insertion hole 33 until the locking blocks 21 and 35 at one end of the first connecting column 25 and the second connecting column 34 are obstructed. At the same time, the upper convex plate support base 22 at the bottom of the second vertical support frame 23 is moved to the required position. Then, the upper convex plate support base 22 is positioned, and the safety protection device is deployed and adjusted. Therefore, through the coordinated operation of the first support component 1, the second support component 2, the first connecting component 3 and the second connecting component 4, the safety guardrail for subway construction can be adjusted in size according to the construction environment, so that it can be installed and used in a suitable manner. This avoids the situation where the size is not suitable and the guardrail needs to be remade. Therefore, the safety protection device for subway construction can be used to isolate the area that needs to be protected in a timely manner and ensure the normal construction on site.
[0034] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model.
